Kovind, Naidu, Modi also paid floral tributes to Ambedkar at a function in Parliament House Lawns here. Lok Sabha Speaker Sumitra Mahajan and several other MPs also paid tributes to the architect of the Indian Constitution.

"The nation is ever grateful to the architect of the Constitution. His wisdom will continue to guide us at all times," Naidu tweeted.

"He championed the cause of marginalised and strove for creating a casteless society. We will be paying a real tribute to Baba Sahebji by establishing a truly egalitarian society and by upholding values and ethics in public life," Naidu said.
